Abstract: 1,193,646. Liquid dispenser. RAINBOW VALVE CO. Ltd., P. T. PULMAN and G. D. S. HORSFALL. 3 Aug., 1967 [16 Aug., 1966], No. 36671/66. Heading A4T. Alcoholic liquids are dispersed as a conical layer by flowing over cone 70 (Fig. 3) into a container 56, so that the conical layer meets the sides of the container and the liquid flows down the inside walls only. Gases escape upwards through the centre of the cone 70 and a hole 75a in the dispenser housing. The locked casing 76 contains mechanism for delivering a predetermined quantity of liquid. On manual, optionally coin-freed, operation of lever 12, the obturator 40 is depressed and releases a valve inside the resilient synthetic or rubber dispensing tube 8, from supply connector 7, so that liquid flows into the container 56, and at the same time tail 50 engages ratchet 58, holding obturator 40 in a depressed position. When filled to an amount predetermined by the screw 66 and calibrated coil spring 61 (Fig. 2), the container depresses its supporting platform 55 at the end of cantilever 54, releasing tail 50 from engagement with the resilient ratchet 58, so that the spring 42 returns the activating arm 38 to its original position, so that obturator 40 rises and closes the valve in the tube 8, cutting off the liquid supply. A transparent U-shaped shield 80, Fig. 10, normally held raised by spring 84, is moved by the lug 90 downwards with the lever 12, so that the shield covers the dispenser 11 and container 56 while liquid flows. The shield is held closed by horns 87 engaging horizontal rods 88 fixed to the tail 50 and passing through slots 89 in the front and rear casing walls. A dash-pot may control the speed of the shield at the closed end. A metering chamber, operated by the cantilever, may be between the dispenser 10 and cantilever 54.

Abstract: 955,226. Pipetting devices. A. KLINGBEIL. Aug. 25, 1960, No. 36689/62. Divided out of 922,062. Heading B1X. In a pipetting device consisting of a ball 32, a tube connector 21, by which a pipetting tube is connected to said ball, both the ball 32 and connector 21 being provided with a built-in ball valve, said connector is attached to the ball by means of a screw connection. The connector is also provided with a side tube having a built-in ball valve. The apparatus is made of rubber or synthetic materials which after curing have the same resilient characteristics as vulcanized rubber. As shown in the Figures to which the above numerals relate, the top part 20 of said connector 21 is provided with a radial flange 22 over which a metallic nut 23 engages. An annular ridge 25 on the valve tube below the cap nut prevents the latter from slipping. Threaded member 29, formed with two radial flanges 30 and 31, is vulcanized into projecting portion 27 of rubber cap 28. Flange 31 contains holes into which rubber flows during vulcanization ; flange 30 may also be thus perforated. Cap 28 is vulcanized to or is a part of rubber ball 32. Connecting pipe 33, integral with the rubber ball, engages in bore 34 of member 29 and is vulcanized on to the inner surface thereof. The device is thus constructed such that after the two parts of the device have been joined no liquid can reach the screw connection members which are preferably made of metal.

Filed: 1930-12-12
Abstract: <PICT:0368838/III/1> Oil is distilled by the introduction in vapour form into a fractionating tower at a point below the lowest stripping section but above a group of bubble trays serving to produce a residuum of flash point greater or equal to that of the fraction removed at the stripping section, the residual oil being transferred to a flash tower maintained under vacuum and having no bubble trays, so that the overhead from the flash tower can be combined with the fraction from the lowest stripping section of the fractionating tower.  Oil heated to about 525 DEG  F. in a tube still 2 is passed through a pipe 3 into a fractionating tower 1 constructed as described in Specification 270,720, [Class 32 Distilling &c.], with trays 89, 93, 94 and stripping sections 91, 92 from which fractions such as kerosene and light gas oil are withdrawn through pipes 19, 21 and condensed in condensers 20, 22.  Vapours pass off at the top through a pipe 8, heat exchanger 9, coolers 11, 12, and separator 13 to a tank 14 from which condensate is returned to as reflux to the tower 1 through a pipe 18.  The residual oil after further treatment with superheated steam admitted through a pipe 7 is removed by a pump 24 and line 25 to a second heater 26 and a tower 28 similar in construction to the tower 1.  Vapours from the tower pass off through a pipe 34, heat exchanger 33, cooler 35 and pipe 36 to a vacuum run down tank 37, the cooler 35 being connected to a barometric condenser 39 and pump 40 by a line 38.  Similarly fractions drawn off through pipes 49, 59, 67, are passed through coolers 52, 60, 68 to run down tanks 54, 62, 70, all of which communicate with a conduit 41 connected to the pipe 38.  Part of the condensate from the tank 37 is returned as reflux to the tower 28 through a pipe 48.  The residues from the tower 28 are evacuated by a pump 75 to vacuum flash tower 77 having no bubble trays above the point of admission of the vapour and supplied with steam through a line 87.  The vapours evolved are passed to a cooler 79 and the condensate is mixed with the fraction removed from the lowest stripping section 100 through the pipe 67, stored in the tank 70.

Title: Improved method for the direct distillation and rectification of wines with the double effect of the heating steam
IPC: B01D3/00
Filed: 1930-12-15
Abstract: <PICT:0369623/III/1> In processes for rectifying wines of the double effect type described in Specifications 107,975 and 189,458, [both in Class 32, Distilling &c.], the distilling and purifying columns are worked under vacuum while the rectification column is operated under atmospheric pressure instead of the opposite way round.  The purification column A, the rectifier C, C<1>, and the distillation column K are arranged in the usual manner the wine being introduced through a valve p and passing through a recuperator L and a small heater M into the column K.  The vapours produced are condensed in a water cooled condenser N and the condensate is fed through a pipe 7 and recuperator J to the purifier A from which it flows through a pipe 12 to the rectifier C.  The necessary heat is supplied to the latter by a steam coil T.  The double effect is obtained by mounting a tubular heater D on the top of the rectifier in which the vapours from the rectifier heat the exhausted vinasses supplied from the bottom of the column K through lines 1, 2, by a pump V, and the vapours evolved from the vinasses are passed through a pipe 5 to the distillation column K for which they provide the necessary heat. The column A is similarly heated from the column C by using the residues therefrom as heating means for the recuperator J through which the condensate on its way to the column A is passed.  In a modification for treating thick liquids such as grain must, the steam condensed in the coil used for heating the rectifier is passed to the heater D where it is re-evaporated and the steam produced is used for heating the distillation column while the thick musts are heated in exchangers by the vapours from the column K.

Abstract: 895,963. Heat treating cast iron cylinder liners. WELLWORTHY Ltd. Nov. 4, 1960, No. 37976/60. Class 72. A method of differentially hardening a cast iron cylinder liner having a flange adjacent one end comprises immersing the liner with the flange uppermost in a molten salt bath at a temperature above the upper critical temperature for a time sufficient to produce martensite on quenching and maintaining the surface of the bath within the bore at or above the level of the underside of the flange while keeping the salt out of contact with the flange to prevent the latter acquiring a temperature above the upper critical point, and then quenching the liner. As shown, a cylinder liner may be supported by a ring having an annular lip 12, engaging the underside of the flange 4, and a surrounding wall 13 in a salt bath 10, the lip and wall preventing the salt from making contact with the underside of the flange though the level of salt in the bore may extend above the level of the underside of the flange. In a modification the liner may be suspended so that the flange is above the molten salt, a cover placed over the liner, and the pressure reduced in the space below the cover to cause the salt to rise in the bore. The liner may finally be tempered. Specification 763,492 is referred to.

The punctiform markings, are, in the described embodiments, produced by light emitting diodes or a CRT or a stylus with which there may be employed photo-sensitive recording material, CRT or a stylus. In a first embodiment Figs. 2a and 2b, signals detected by ultrasonic apparatus 14 from angle probe 4 are fed through amplifiers 19a and 19b which have their gains arranged to enable triggers 20a and 20b when signals have amplitudes above a lst level and a 2nd higher level, respectively. Control circuit 18 then activates the LED 17a or 17b most closely corresponding in position to the projection of the reflection 2a or 2b on the position array holder 15, at a high or low intensity corresponding to the strength of reflected signal as detected by amplifiers 19a &c. It is stated that several levels may be detected, and, to give an indication that the apparatus is operating, until detection of a strong reflected signal, LED's 17 may be made to glow faintly, where, after only that diode corresponding to the strong reflection is enabled. In a second embodiment Figs. 6a and 6b (not shown), a separate linear array of diodes is provided at right angles to the diode array denoting position, which are arranged to display the amplitude of the reflected signal increasing orders of amplitude corresponding to increasing number of illuminated diodes. In a third embodiment Figs. 7a and 7b (not shown), the position array (15) may display the amplitude of a reflection - a strongly illuminated diode (17a) - by the number of weakly illuminated diodes (17d) adjacent thereto. In Figs. 8a and 8b this configuration is associated with photo-sensitive material, the diodes 17 are arranged on the lower side of holder 15, and a radially variable polar plot of the inhomogenity producing the reflection 2 resulting in the illumination of diode 17a, is made by rotating the apparatus with diode 17a as the centre. In Figs. 9a and 9b (not shown), a parallel plot is made in a similar manner using translational movement of the apparatus. In a fourth embodiment Figs. 10a and 10b (not shown), the probe of Figs. 2a and 2b is utilized with miniaturized, portable, battery powered control circuitry.

Abstract: 372,831. Slicing bread &c. HARTMAN, W. W., 701, N. Main Street, Los Angeles, U.S.A. Dec. 19, 1930, No. 38371. Convention date, Feb. 17. [Class 5 (i).] Loaves 105 are placed upon an endless band conveyer 20 that carries them to a downwardly inclined platform 95 formed by rods from which they are lifted one by one by a rotary inverting device 94 and delivered, bottom outwards, into the cells of a rotary carrier 19. This carrier is formed by a series of annular members 50 maintained in their relative positions by riding in grooves in supporting rollers 18 carried by a frame 17. The carrier is rotated by bars extending between radial arms 79 on a powerdriven shaft 76 these bars engaging the sides of recesses 73 and pins 50a on the annular members 50. The loaves are thus carried to the slicing device comprising notched reciprocating blades 33 moving between the members 50 and driven by eccentrics 30 mounted on a shaft 27. Springs 34 may be arranged at the upper ends of the knives and wearing pieces 41 arranged in their upper guides. The eccentrics are arranged in pairs set 180‹ apart and the pairs are uniformly angularly distributed along the shaft. The loaves are held laterally while being sliced by providing each loaf containing compartment with a cam-actuated plunger 55 carrying a loaf-engaging plate. These plungers are pressed outwards by springs but are forced inwards by a cam 80 to hold the loaves while they are cut and while a cardboard tray 74 or similar binding device is applied to the base of each sliced loaf. The cutting device and the carrier are so arranged that the loaves are presented to the knives bottom corner first and the rotary movement of the carrier is slowed during the beginning of the cutting operation. Each cutting blade 33 has a bevelled edge 47, Fig. 7, formed with notches 46. After slicing the loaves are conveyed by the carrier under spring wires 84 that hold them in the cells of the carrier until they can be delivered on to an endless band conveyer 124 which delivers them to a wrapping machine. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which a loaf is placed by hand on a pivoted carrier which is then manually swung forward across the line of action of slicing knives. This subject-matter does not appear in the Specification as accepted.
